JAMES R. BREWVSTER AND ORLANDO E. WILLIAMS, OF WINDSOR, VERMONT.

MITER-BOX.

SPECIFICATION forming part of Letters Fatent No. 369,770, datedSeptember 13:, 1887. Application filed July 27, 1886. Serial No.209,242. (No model.)

To all whom, it may concern:

Be it known that we, JAMES R. Bnnwsrne and ORLANDO E. WILLIAMS, citizensof the United States, residing at Windsor, in the county of \Vindsor andState of Vermont, have invented certain new and useful Improvethefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked zhereon, which form apart of this specificaion.

The invention will first be described in con nection with the drawings,and then pointed out in the claim.

Figure l of the drawings is a perspective view; Fig. 2, a verticalsectional elevation; Fig. 3, a plan view. Fig. 4 is a perspectivespective view of the top.

In the drawings, A represents the bed of the miter-box, preferablyprovided with three legs, a a a, of which the front one is perforated,so as to be fastened by a screw to a workbench.

B B are swinging arms, end pivoted on the same center, as shown in Figs.1 and 2 of the drawings, or on different centers, as shown in Fig. 3.

b are end cams, by which the arms maybe fastened to the bed A, which maybe a whole or a part circle, the latter being sufficient for the arms toswing forty-five degrees and be fastened.

O G are the saw-guides, and D D the posts in which they are held. Theguides C are made in two pieces, as shown in the drawings, which, whenplaced together, form the sawback slot 0, the slot 0, which prevents theteeth from touching any part of the guide, and the slot 0 for the plateor body of the saw, while the teeth travel in the spaces 0. The twoslots 0 c in the two guides are arranged diagonally opposite to oneanother, one guiding the upper part of saw-plate and theother the lowerpart thereof, just above the teeth. This more effectually prevents theblade from the saw-guides connected at getting at any part out of aperpendicular plane than if both were placed near the back or near theteeth. The screws 0% serve to keep the saw-plate perpendicular. Theguides have a tenon, c and vertical grooves 0* 0, while the postsconsist of a bar, d, grooved to receive the guide-tenon c" and rivetedsteel plates d d, extending over said groove toward each other, so as tohold the tenon 0 The bars d are provided with right-angled flanges dwhich are fastened to the bed A. Thus it will be seen that the posts arefixtures on the base,while the guides are held to the posts by avertical tenou-and-groove joint, so that they may be readily detached oradj usted. The guides may be connected at the top bya horizontal bar, E,so that they may be moved up or down together and exactly the samedistance; but it is not absolutely necessary, and may be omitted, asillustrated in Fig. l of the drawings.

F is a stop or rest for the saw-back, and has a longitudinal slot, f,through which passes the screw d which clamps it to the post D. Byloosening this screw it may be adjusted on the saw-guide. This stop orrest has a short arm, f, at right angles thereto, and bent to conform tothe shape of the guide; also at one side an arm, f bent at right anglesto the plate and extending out sufficiently to support the saw-back.

Our posts I) require no fine fitting, and are easily brought to theirexact perpendicular, while the guides allow the saw to be always kept ina perpendicular plane.

We thus make a moderately-cheap miterbox which will do perfect work andbe little liable to get out of repair.

The primary object of the saw stop or rest is to barely allow the saw topass through the.

material sawed without coming-in contact with the bottom of themiter-box. The saw-back comes in contact with the arm of the stop orrest, and is thereby stopped. By making the rest adjustable it isadapted to saws of different width and for sawing tenons or similarwork, the rest being adjustable to stop the saw at any point.

What we claim as new, and desire to secure by Letters Patent, is-

In combination with a miter box bed and two vertical posts havingvertical grooves, spaces 0 in which travel thesaw-teeth, as [o the twosaw-guides having tenons reciprocatshown and described.
